In one of the last posts I’ve showed you how to install Let’s encrypt certificate on PRTG. Now it’s time to renew it. Process is simple, but require manual work.
- Start letsencrypt.exe and choose S for Renew specific
- Enter the number of the certificate you wish to renew
- If certificate renew process went successful, you’ll see this screen
Now open PRTGCertImporter.exe and import certificate like in previous post.1
